Cape Town - They're part of Africa's most critically endangered species, and their greatest enemy is typically the human race.
But in this rare footage captured in the Kruger National Park, two white rhinos turn on one another in a brutal fight.
According to Susan Meyer, the woman behind the camera, their game viewing party "really thought the one rhino was going to kill the second one!"
She says on the Kruger Sightings YouTube page that they were the first people to come across the sighting. "We came across two rhinos, which seemed to be fighting. The one was lying on the ground while the other one was constantly stabbing it with its horn.
"This was quite disturbing to see, as you can imagine. At one stage we thought that the one was going to be killed for sure," Meyer says.
Despite their worries, the rhino gets up and tries to escape its attacker, that's in hot pursuit. Eventually, the rhinos end up in a small pond... but there's another surprise waiting...

An unsuspecting hippo, resting in the pool where the rhinos splash into, quickly realised it's unwanted presence, and dashed out.
Luckily, the water seemed to subdue the aggravated rhinos somewhat.
"They were exhausted and seemed like they didn't have any energy left to continue their scuffle," Meyer remembers.
"The whole ordeal was quite traumatic to see and I really hope that I never have to witness anything like this again. The screams of the injured rhino was a horrible sound to witness," she says.
Black rhinos are typically characterised by their extremely aggressive behaviour. They will regularly fight each other, and have the highest rates of mortal combat recorded for any mammal - about 50% of males and 30% of females die from combat-related injuries.
But the rhinos seen fighting in the footage above, strangely, are white rhinos! According to Cornel Rademeyer, a Kruger traveller and guide, white rhinos are known to be a "bit calmer, but also need to fight for breeding rights and territory".
